What is the potential result of applying fertilizer during high heat?

Applying fertilizer during high heat can lead to an increased risk of plant damage. When temperatures are elevated, plants can experience stress, making them less able to efficiently take up nutrients. This stress can exacerbate the effects of fertilizer application, which might lead to burning of the roots or foliage, nutrient imbalances, or overall plant decline.

High temperatures can elevate the metabolic rates of plants, but they can also cause water stress, making it challenging for the plants to absorb and utilize the nutrients from the fertilizer appropriately. Under such conditions, the added salts in fertilizers can concentrate in the soil, further stressing the plants.

Understanding the timing and conditions for fertilizer application is crucial for promoting plant health, particularly in regions like Ohio where weather fluctuations can significantly impact garden and landscaping efforts.
